Letters Patent No. 62,142, dated February 19, 1867.

IMPROVED MACHINE FOR SGOURING MARBLE.

T0 A LL PERSONS TO WHOM THESE PRESENTS SHALL COME:

p Be it known that I, HENRY C. LL'LI., of Montpelier, in the county of Washington, and State of Vermont, have invented a new and useiul Machine or Apparatus for Securing or Reducing Marble or other stone; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a top view.-

Figur'e 2, a side elevation and Figure 3, a longitudinal section'ofI it.

In such drawings, A denotes a heavy block of cast iron, or other proper material, formed with a sandreceiving chamber or space, c1, in its upper part, and also with a step, b, to receive thejournal c, of a swivel, B, to which a long handle, C, is jointed at one end, From the receivingwhamber a, a series of holes, d d d, lead down through the block A, and Jthere is placedin the top of the block, and so as to extend down into it, and around the step b, a pyra-midal tunnel, D, havingl perforations through it about the said step. There is iixed on the handle C a water-vessel or reservoir, E, from which there extends a pipe, a, terminatingr in a rosejet,f, such being arranged with respect to the tunnel D in the manner as represented. There is a stop-cock, q, on the pipe e, and there is also a small filling tunnel or mouth, '11, to the ves-sel E. Preparatory to the machine or apparatus being employed for scouring or reducing a sla-b orblock ot' marble, the reservoir E should be charged with water, and the space a should 'be supplied with sand or other material to bc used in grinding or scouring the surface ofthe marble. The stop-cock being opened so as to allow the water to flow in suicient quantities into the tunnel, a workman is to take hold of the handle and more the block A back and forth on the surface to be scoured or reduced, the sand, emery, or material used for abrading the surface, being supplied to the receptacle a as fastl as may be necessary. The water received into the tunnel will be directed into the space a, 4

and will flow therefrom withthe grinding onscouring material. When desirable, the tunnel may be employed to hold a finishing material finer than'that designed tobe used in the part a. As the' step I is arranged nearer to one than the other end of the block A, the operative, by slight changes of the angular position ofthe handle relatively to the grinder or hlocl: A, will ind it easy to revolve the said block while moving it back and forth, and thus he can produce movements of the block by which it will be `caused to reduce the stone to a plane surface without fnrrows. The machine or apparatus so made is a very eiieient one for the purpose for which it is intended.V It may also be used at sea for scouring or cleaning the deck of a. vessel, and will also answer on shore for scouring a door, but itis designed specially for the scouring of marble.

I claim in the said marble sconrer the combination of the handle,` the troughed bloeit, and the water vessel, constructed, arranged, and appliedtogether, substantially in manner and so as to opera-te as speciiied.

I also claim the combination as well as thc arrangement of thc perforated tnnnclfwith the troughed block, the handle, and the water vessel, Constructed, arranged, and applied together, substantially in manner and so as to operate as specified. i
